VACUUM CLEANER.

Application led April 23, 1927. Serial N0. 186.084.

A further object of the invention is to rovide a construction of this character, w ich permits a device of this type to be employed in combination with a rotatable brush arranged in the mouth of the nozzle, such as is now employed with certain types of vacuum cleaners. v

A further object of the invention is to produce a device of this character which may be readily and cheaply incorporated in the vacuum cleaner construction, which Iwill be durable and efficient inservice and a general improvement in the art.

These and other objects I attain by the construction shownin the accompanying drawings, wherein for the purpose of illustration is shown a preferred embodiment of my invention and wherein Figure 1 is a plan viewnpartially broken away of a vacuum cleaner constructed in accordance with my invention; y

Figure 2 is a side elevation thereof, portions being broken away to show the interior construction.

Referring nowv moreparticularly to the drawings, the numeral 10 indicates a motory casing of the vacuum cleaner, 11 the casing of a, suction fan driven from one end of the armature shaft 12. and 13 the casing of a pulley 14`secured to the opposite end ofthe armature shaft. yExtending from/the intake v of the fan casing 11 is a suction nozzle 12, the

terminal portion of which confronts the surface over which the motor 10 is passing in' the usual manner. Arranged within the mouth of this suction nozzle and rotatably supported by the end walls 15 thereof is a brush 16, which maybe ofany usual or preferred construction.

In accordance with my invention, one end wall 17 of the suction nozzle is continued downwardly and rearwardly from the suotion nozzle te form the end wall of a compartment 18, the upper wall of which is formed by the bottom wall 19 of the suction nozzle or 4a continuation 2O thereof. The compartment 18 has a second end wall 21 and a rear wall 22," the lower ends of which terminate in the same plane as the mouth 15 yof the nozzle. Mountedin the end walls 17 and 21 immediately to the rear of the bottom walls 19 o f the nozzle at the mouth thereof is a roller R having longitudinally spaced cam elements 23. Secured to the rear Wall and extending forwardly in the plane ofthe lower edge of Athe walls ofthe compartment 18 are spring tongues 24, each having at its forward end an upturned end portion provided at its extremity with a tip 25 extended into the path of one of the cams 23. The roller R is driven by a belt 26 from the pulley 14 and this roller is in turn connected with the brush 16 by a belt 27. The 4spring lingers 24 are made as narrow as possible and the cams 23 may be either uniformly spaced about the roller R, or vmay loe arranged in groups, which are uniformly spaced, so that no sudden load will be thrown against the mechanism of the vacuum cleaner toV prevent a smooth operation thereof.

It will be obvious that as the roller rotates, the'forward ends of the springs 24 will be elevated by engagement of the cams 23 with the rearwardly directed terminal portions 25 and after being placed under tension, will be suddenly released, so that they will move downwardly and engage the surface over which the cleaner is passing. A

Vtapping action is thus provided, which will serve to jar loose from the surface particles of dirt, which otherwise would adhere thereto with suicient force to prevent their removal either by the brush or suction nozzle.

It will ofcourse be understood that the entire structure will be mounted upon suitable casters 28 and provided with the usual handle 29.

Since the construction hereinbefore set forth is capable of a certain range of change and modification without materially departing from the spirit ofthe invention, I do not limit myself to such specific structure except as hereinafter claimed.

I claim .F

lIn a vacuum'cleaner, a supporting frame, a motor thereon, a pump casing having a pump therein operated-by the motor, a nozzle connected to the casing and in communication with the pump, said nozzle being extended laterally from the casing and terminatingl in a downwardly directed elongated suction mouth, a support beneath the nozzle and ofI said fingers and suddenly` releasing the spaced from the nozzle mouth, a plurality of same, and an open-bottomed housing for said lingers secured at one end to the support With fingers comprising in part the bottom Wall 10 their free ends terminating in hooks adjacent of said' nozzle.

5 to and in a line parallel to the nozzle mouth, In testimony whereof I hereunto affix my means operated by the operation of the mosignature. tor for intermittently elevating the free ends JOHN E. ARDELL.
